This product is meant to be used on a daily basis with students to practice basic mathematics concepts. If used everyday in the classroom, it will run 13 weeks or until winter break on most calendars. There are skills ranging from fractions and decimals to place value and average, and everything in between! This product has cyclical review so students are practicing the same concept for many weeks to ensure that mastery is reached. It is a great product to use as a warmup at the beginning of class. Each sheet has 20 problems or 4 problems for 5 days of a school week. After about 5 weeks of practice, assessments are provided to test students' mastery. Each assessment has 1 problem for each concept taught during those 5 weeks (about 12 concepts).
